Can't u space the vertical mounting holes to suit and use longer bolts?
i've had to have parts made before

trying to explain to someone when it would be quicker to do it yourself.i was in engineering 12years ago and its very fustrating
Try a small local firm state its 4 cash,and state exactly wot u want,and don't be put off by bull that sould only take an hour tops.
Good luck
Paul
